RE: Conditional logic in SQL SPs

[Bruce, Rodney S Mr CTR USA AMC]

Maya,

        Thanks for the reply.
        Yep, I know about the IF....ELSE...

        But I need more conditions:

        IF  @Myvar = 1

        ELSE IF @Myvar = 2

        ELSE
                for anything else


        With just the IF....ELSE...
        The only way I can get it to work is to add a control var

        @control = false

        IF @Myvar = 1
                @control = true
        
        IF @Myvar = 2
                @control = true

        IF @control = false
                Do this


Just wondering if the IF....ELSE IF.....ELSE was possible.
Or if I am missing a better way.

Thanks
Rodney

You can use IF - ELSE
IF Boolean_expression
 BEGIN
   { sql_statement | statement_block }
 END
ELSE
 BEGIN
{ sql_statement | statement_block }
END

Hope this helps

Hi,

 Does SQL (MS SQL 2005) SPs allow/have: IF ELSEIF ELSE, structure?

 IF  something = 1
 ELSEIF something = 2
 ELSE something = anything else


 OR
 a SWITCH/CASE?


 I can find examples for inside a query
  Select f1,f2
  Case f1
   WHERE '1' then this
   WHERE '2' then something else


 But can not find an example for:


  CASE  @MyVar
   WHERE '1' then
    BEGIN
     Select *
     From Mytable
    End
   Where '2' then
    Begin 
     Select *
     From Mytable2
    End


Any help would be appreciated.
Thanks
Rodney
